  • Degassing Refrigerators - Drill-head and Piercing-plier

    1. For what purpose do we have to degas a refrigerator? A refrigerator has to be disposed as hazardous waste. The refrigerants inside a hazardous refrigerator are harmful for the environment (ozone depleting and greenhouse effect). Most common refrigerants are; R12, R134a and R600a. The uncommon is the removal of NH3. Refrigerants are developed to dissolve very easily into ...

  • Annual European Union greenhouse gas inventory 1990–2013 and inventory report 2015 - Submission to the UNFCCC Secretariat

    ES.1 Background information on greenhouse gas inventories and climate change The European Union (EU), as a party to the United Nations Framework Convention on Climate Change (UNFCCC), reports annually on greenhouse gas (GHG) inventories for the years 1990 to t-2 for emissions and removals within the area covered by its Member States (i.e. domestic emissions taking place within its ...

  • Methane emissions and airflow patterns along longwall faces and through bleeder ventilation systems

    The National Institute for Occupational Safety and Health (NIOSH) conducted an investigation of longwall face and bleeder ventilation systems using tracer gas experiments and computer network ventilation. The condition of gateroad entries, along with the caved materials permeability and porosity changes as the longwall face advances, determine the resistance of the airflow pathways within the ...

  • SF6 Nameplate Inaccuracies and their Impact on Greenhouse Gas Reporting

    Abstract With emission reporting now being mandatory for many SF6 users, reports of nameplate discrepancies have become quite common. This paper will identify the different types of emissions, discuss the possible reasons for some of the inaccuracies, as well as the difficulty faced by both SF6 users and regulatory agencies alike while trying to gather accurate data. A simple method to ...

  • ADMS 5 Buildings Validation AGA Experiments

    The American Gas Association (AGA) experiments1 [1] occurred during spring and summer 1980 at gas compressor stations in Texas and Kansas. At each test facility, one of the gas compressor stacks was retrofitted to accommodate SF6 tracer gas emissions. In addition, stack height extensions were provided for some of the experiments (with the normal stack height close to 10 m). The stack ...

  • An Overview of the F-Gas Regulation Proposals

    By now you should have an appreciation of F-Gas regulations and what it means to you. But in case you don’t, here’s a quick overview in relation to leak detection. Why have the F-Gas regulations come into force? Fluorinated greenhouse gases (F-Gases) are potent greenhouse gases that contribute to global warming and are sometimes referred to as High ...

  • New Assembly Plant Inaugurated

    Aerzen Hungária Kft. In the company of many guests, the Hungarian subsidiary of Aerzener Maschinenfabrik in Esztergom officially inaugurated the new location of the process-gas-division, which includes a new office building and an attached assembly building, on 12th April 2013. At the beginning of 2011 it was decided to establish a process gas location in Hungary which ...

  • GHG quantification reporting and lifecycle assessment: does one size fit all?

    Corporate and government entities have been developing and reporting greenhouse gas (GHG) emission inventories, some for well over a decade. The basis for developing these inventories has evolved from voluntary mechanisms (e.g., sustainability reports; registries like the DOE 1605(b) or The Climate Registry) to regulatory requirements (e.g., EU Emissions Trading Scheme, US EPA Mandatory Reporting ...

  • Smart LDAR — more cost-effective?

    On December 19, 2008, EPA issued a final rule establishing a voluntary Alternative Work Practice (AWP) to detect leaks of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from process equipment (FR Vol. 73, Number 246), thereby providing the regulated community additional flexibility in complying with leak detection and repair (LDAR) requirements. The AWP allows owners or ...

  • F gas regulations aim to improve climate and reduce global warming

    Fluorinated greenhouses gases, also known as F Gas, are being closely regulated by the United States and many other foreign countries because they can cause harmful climate change. The U.S., Canada and member countries of the European Union have imposed regulations aimed at containing or phasing out certain substances that increase global warming. F Gas is commonly found in stationary ...

  • EPA mandates proper refrigerant gas recovery processes

    New EPA regulations require facilities that use air conditioning and refrigeration equipment to have a refrigerant recovery plan in place. The plan is needed to make sure that any harmful gases that might leak are captured. Refrigerant gases contain hydrochlorofluorocarbons, known to cause severe damage to the ozone layer and to promote global warming. A comprehensive plan is now in place to ...
